Application October 1.9, 1934, Serial No. 749,061 13 claims. (01.299-149) This invention relates to a combined hose valve and nozzle, more particularly designed for use in washing automobiles and the like. `'I'he principal object of the invention is to provide a combined hose nozzzle and valve by means of which the user can easily and continuously regulate the amount of flow through the nozzle to suit the particular work being done, and can also control the type of spray or stream being delivered by the nozzle. Thus, a hard strong stream can be delivered for washing `mud and grease from the automobile chassis, or a soft slow stream can be delivered for sponging the more delicate finish ofthe automobile.

16 Other objects of the invention are to provide a simple, economical nozzle and valve construction which can be completely controlled by one hand allowing the other free for washing work; which will automatically shutoff when not in use; which cannot become .damaged by careless use; and which will not injure the finish of the automobile. y i

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency.

1 These will become more apparent from the following description. f

The invention comprises: a relatively short piece.of flexible hose I0, of rubber, fabric, or any other suitable material, on one extremity of which, a valve housing II is fixed.` At the other l extremity of the hose Il! a nozzle I2 is secured. Intermediate the extremities of the hose is a ball I3 of rubber or other suitable material. The ball I3 may be secured to the hose in any desired manner. As illustrated', it is molded onto a metal- 55 ne sleeve 4 which is then clamped to the hose suitable supply hose.

extremity and turned inwardly to form a flange I5 whichholds the ball in place onthe hose. The nozzle I2 comprises a hollow cylindrical shell terminatingfat one extremity in a hose nipple I6. The nipple I6 is of smaller diameter 5 than the shell and is permanently fixed into the extremity of the hose I0. The other extremity of the shell is internally threaded to receive a stream adjusting tube I1 which extends beyond the discharge extremity of the shell. The exl0 tending beyond portion of the tube I'I is enclosed in a protecting rubber sleeve I8. This sleeve I3 may be molded directly on theshell, and is preferably held in place thereon by splitting the extremity of the tube I1 and turning one-half of 15 the split outwardly into the rubber of the sleeve and the other half inwardly to form a peripheral flange 31.

The tube I1 acts to holdin place a nozzle controlling member IS. The controlling member I9 20 is formed with spider-like projections 20 at one extremity which guide the member within the shell I2. The other extremity is beveled to form a tapered valve which can be forced into the open extremity of the hose nipple I6. A compression 25 spring 2I constantly urges the member I9 outl wardly and the threadedtube l1 is employed to In the following detailed description of the in- Y,

force it inwardly. 'Ihe controlling member I9 is formed with a conical water passage 22.

The valve housing II terminates in a threaded 30 socket 23 for receiving the hose connector of any 'I'he interior of the housing is formed .with a valve bore 2l of smaller diameter than the socket 23 terminating in a valve seat 25. A water passage 26 communicates be- 35 tween the valve bore 24, and the hose I0 through the valve seat 25. The valve housing is preferably secured to the hose by slipping the latter over an externally-toothed nipple 26, and then rolling or spinning an internally-toothed sleeve 21 40 thereover. In this way the hose is permanently secured to the metal of the housing I I.

The valve consists of a stem 28 which extends freely into the flexible hose I0. The stem 28 ter- 45 minates in a cupped, valve disc 29, in which, a resilient washer 30 is held by means of a conical retaining ring 3|. The valve disc 29 is formed with projecting tongues 32 which space it from the cylindrical interior of the valve bore 24. The valve is retained in the housing by means of a metallic retaining washer 33 provided with a shouldered recess 3l for receiving a fine mesh, metallic screen 35. The retaining washer 33 is held in place by means of a rubber hose gasket 36 which seals the joint to the supply hose connector.

Operation fortable hand grip. A simple twist of the ball I3 to any side flexes the hose I and tilts the valve disc 29 from its seat 25, as shown in Fig. 3. This allows the water to flow between the tongues 32 and under the valve into the hose I Il. The flow may be stopped by simply allowing the hose I0 to straighten so as to release the valve stem and allow the valve to return to its seat. The conical ring 3| acts to guide the valve to a concentric position on its seat.

If a hard stream is desired for heavy washing work, the tube Il is rotated to force the control member I9 against the passage through the hose nipple I6. This allows the stream to be projected directly through the conical passage 22 and through the tube I1 in a small hard stream, without contacting the walls of the latter. Should a softer stream be desired, the tube I1 is rotated to allow the valve member I9 to separate from the nipple I6. The water can now flow both through and about the control member in a broken stream. 'I'his stream is still further broken by striking the peripheral ange 31 so that it exists in a harmless defused spray for supplying a sponge or similar uses. Any intermediate condition can be obtained by proper adjustment of the tube I'I.

The screen 35 acts to prevent foreign materials from entering the valve, to defuse the incoming stream, and to prevent dripping or dribbling from the valve. venient finger grip for adjusting the tube I1.

The spring 2|, in addition to actuating the control member' I9, acts to lock the tube II in its threads so that it will stay set at any desired position, regardless of where.

While a speciiic form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
